There are a number of Phoenix-area shops that sell kayaks.
Dick’s Sporting Goods, REI, Cabela’s, and Bass Pro Shops are the most common retailers. You’ll also occasionally find kayaks at Costco, Wal-Mart, and Sam’s Club. You can also buy kayaks from a number of sites online.
In addition, kayaks are great to find on the used market too. Check out craigslist, Facebook Marketplace, Offer Up, and similar websites for additional deals. Buying a used kayak is an excellent way to get into the sport without spending too much money. In fact, you can often later resell the used kayak for roughly the same price you originally bought it for.
In addition, there is an annual “Paddlefest” at both Lake Pleasant and Lake Havasu City that feature a number of kayak models you can take for a quick spin on the water. This is a great way to test out various kayak lengths, styles, and features before you buy.
